discount tire doesnt list 555's in the size he wants for the rear.
in 275/40/17 the 555's are $166, $16 more than the drag radials and ALOT more than the hankooks.
Maybe that's why your run 14.0@104...

J/K I couldn't rate the Hankooks, ... haven't seen them.
Honestly, I may not be the best person to take advice from, unless you are an extremist when it comes to tires. When I go autocross, I change my street tires, Nitto 555RII 275/40/17 (R Compound race tire rated at 100TW) for some HOOSIER DOT RACE tires that last just under ~100laps for about $1050US.
I can say that out of the many tire types I've tried, the Nitto 555 are highly recommended for all around use. Very good price for the kind of tire you get. Azenis 615 are great as well, but don't last as long. I got about 5000miles out of mine vs 10000+ on the Nitto 555. So there is more value in the Nitto 555. I can also recommend the Kumho MX. Good traction, and good treadware.
The 555RIIs - which are light years ahead of anything on the street - are the most impressive to me. I've gotten 4000miles out of them right now, and they should be good for another 4000 from the looks of it. I've gone through 2 weekends of autocrossing with them (Hoosiers are toast for the season)... and they seem to take the beating as long as you cool them in between runs. If they become to hot, they loose composure and start loosing chunks along the way. But these tires stick SO much, I make modified S2000s look slow at AutoX.
